Detailed Description
Product Code: Ytc Product Name: Ceramic grade zinc oxide Molecular formula: ZnO Molecular Weight: 81.39 Theoretical nature: White or yellow powder, density 5.606, melting point 1975 ° C, is a gender oxide, insoluble in water or ethanol, soluble in acid or alkali solution. When high-temperature yellow, cool white resume. Uses: Ceramic grade zinc oxide for the development of ceramic pigment, ceramic glaze frit production and firing. Zinc oxide can also be used for such high-grade glass production. Features and functions: 1, "Yunfeng" brand low coefficient of expansion of zinc oxide, used in ceramics production process, with good heat effects of vibration and mechanical vibration. 2 large specific surface area, high opacity, good color resolution of the base material on the surface of the color of ceramic products. 3, low iron content in the item index Model Htc071 Htc072 Htc073 Htc074 Htc075 Htc076 Htc077 Htc078 zinc oxide (dried basis) (ZnO)% ≥ 99.8 99.7 99.5 99 99 98 96 90 metal (in total Zn)% ≤ No No No 0.02 0.02 No No No lead oxide (Pb)% ≤ 0.005 0.037 0.15 0.005 0.06 0.18 0.2 1 iron (Fe)% ≤ 0.0001 0.0001 0.0001 0.0001 0.0004 0.0002 0.001 0.001 hydrochloric acid insoluble matter% ≤ 0.006 0.008 0.012 0.02 0.02 0.05 0.1 1.2 loss on ignition% ≤ 0.1 0.2 0.2 0.2 0.2 0.4 0.8 1.2 105 ° C volatile substances% ≤ 0.2 0.3 0.4 0.5 0.5 0.6 0.8 1.2
